Yellow leaves with brown spots

[Bombard]

Hi all. First time posting here. I have three AK-48 in organic soil. Have been growing according to the book TLO gardening. yes I am in the eight week of flower and for the last two weeks the fan leaves have started to yellow with brown spots. I added cal-mag two waterings ago. Do the fan leaves die off closer to finishing or do I have a dificiency?

Do you PH your water? Pics look like new growth is good...have you flushed it yet? Buds look kinda small, what kinda light are you using?
